The phonograph disclosed herein is animprove-l ment of that shown in the said Smyth patent in that upon proper preselection this phonograph lwill effect reproduction oi either side of the selected record, while the phonograph disclosed in the Smythpatent can only eilect the reproduction of one side of a selected record. Since certain elements, assemblies, and `arrax'igements oi Yand turntable reciprocating arm T; cam operable reproducer means U returning the record reproducing means H to its starting position upon the completion of a playing of a record; record turning mechanism driving means V and control devices, which are 'generally designated as W, X,

the phonograph have been described in the above for the reproduction of a record. 'Ihe record t changing mechanism .shall be understood to include the record selecting and delivering mechanism which selects and ldelivers a preselected record to the reproducing means for reproduction. The record selector and selecting mechanism shall be understood to include the part of the record changer which accomplishesthe selection of a` predetermined or preselected record to be odelivered by delivery means to the reproducing means. The record preselecting or selector control shall be understood to include the manually operated elements and associated structure vby which records are preselected. The record turning mechanism, which in certain instances comprises a part of the record changing mechanism,

Phonographs of the class to which this invention is particularly adapted are generally, but not necessarily, controlled by coin operated means such as the coin feed receiver or slide 3| which delivers a coin to a coin slide or chute 32. The

coin operated means comprises a switch arm 33 (shown in Figure 2) swingable about a pivot 34.

when engaged by a coin in the slide 32. This eects closure of the contacts 35. The contacts 3l control an electrical circuit from a suitable source of electrical energy which is connected to leads 30, and thus energize an' electromagnet 31 on the control device W to egect operation ofa pawl 33 which in turn actuates :a ratchet 39. A pin or stud 40 on the ratchet 39 normally engages Aa switch operating arm 4i for holding switch' contacts 42 open. When the ratchet 39 is actuated by the pawl 3B, it releases the switch operating arm 4i and permits the contacts 42 to close.

The closing of the contacts 42 closes a circuit from A circuit from'the source of electrical energy to shall be understood to include that portion of the 4 mechanism which turns a preselected record so as to reverse the side or face of the record which is adjacent the tone arm or pick up'.

the cam driving means N through normally closed contacts 43 ofthe control device X. 'The masterv cam M is rotated by the cam driving means N and drives its shaft 4l as wellas the notched disk 4l of the control device X( The Arotating master cam M engages the'cam follower S to raise' the reciprocable slide R which carries with it the 1 turntable reciprocating arm T. 'This raises the rotating turntable G'. If one of the record carriers J is in position for cooperation with the upwardly` moving turntable, the tiu'ntable passes through that record 'carrier and removes the'record therefrom. The turntable then continues its upward movement to bring the record into playing engagement with the record reproducing means-H.

When the master cam M has rotated suflicient-4 ly to bring the turntable G into playing position,

the shaft-4l has rotatedthe notched disk 4l tol toward the notched disk 43, the registry of the notch with the cam portion of the switch arm 'permits the normally closed contacts 43 to open.

In reproducing a record the reproducing means H swings inwardly on the record toward`the center thereof. This movement ofthe reproducing means H' rotates a' shaft 43 and. drives a n notched disk "which is carried by the shaft 43. 'lllienotcheddisk 43 constitutes a part oi the control device Z and has .a projection ll thereon.' whichv swings with the reproducing Afollower u m" the notched disk ""Ui control 49 has registered with a cam portion of switch contacts 53. Upon such registration of the cam portion of the switch operating arm 52, with the notch in the disk 49 of the'control device Z, the normally open switch contacts 53 close'to thereby close a, circuit from the power source to the cam driving means N. Thiseifects rotation of the master cam M and its shaft 45. e

When the rotation of the master cam M is thus resumed, the cam follower S, which is engaged `by the cam track and the slide R, which carries the follower S, are moved by the cam in a direction to cause the turntable reciprocating arm T to move the turntable G away from the reproducing means Hand back through the positioned record carrier J to deposit the reproduced record thereon. `The reproduced record has thus been moved out of playing engagement with the reproducing means H. A pin or stud 54 (Figure 22) on the rotating master cam M engages the reproducer return means U and actuates it to swingrthedisk 49 by engagement.- with the projection This returns ,the reproducing means H to its starting position.

During the rotation of` the disk 49 in the return movement. of the reproducing means H, it` rcams the switch arm 52 to open the contacts 53.A This opening ofthecontacts -53'does not, how.

ever, result in the stopping of the cam driving lmeans N because before they are opened the rotation of themaster cam M and theshaft 45 have caused sumcient rotation of the notched disk v46 of the control device X to move the notch in that diskout of registration with the cam portion of switch operating arm 41. This rotation vof the disk 46 causes the switch contacts 43 to close a power circuit to the cam driving means N before the contacts 53 are opened. /I'he cam driving means N consequently continues to drive the cam means M and its shaft 45 and also to rotate disk 46. When the rotating master cam-M has completed its movement of the cam follower S, the slide R and the turntable re-V ciprocating arm T, the turntable is returned to its normal position of rest. When the turntable is returned to its normal position of rest, a' pin or stud 55 on the rotating disk 46 of the control device X engages a suitable pawl structure (not shown) to effect a single notch return movement of the ratchet 39. y If the ratchet 39 has been moved only one notch by the deposit of a single coinnthisreturn movement effects reengagement of the switch operating arm 4| by. the

Din or stud 40 to reopen the contacts 42 and thereby stop the rotation of the turntable rotating means O and the cam driving means N.` .The cycle of operation may be repeated by the subsequent deposit of an additional coin and will repeat itself if an additional coin has been de- Dosited during the reproduction of the `preceding record. e

'I'he operation of lthe phonograph, which has been thus far described, presupposes the preselection'of a side of one of the records in the stack,

which is normally facing upwardly toward the reproducing means H in the stack. This much of the operation is quite similar to that described in the previously mentioned Smyth-patent, No. 2,159,834. In the present phonograph, however, as will be more clearly understood from the description of the additional operation of the present phonograph, it is desirable that the reproe arm 52 which controls the normally open switch Vspect to the record withthe ducing means H is heldin a normal position away from the turntable G and a record which is carried' thereby until such selected record is in proper 'position for reproduction of the selected sideof that record. To accomplish this holding of thev reproducing means H away from the record surface between the reproductions of records and during the record selecting operations, the re producing means H has a notched bracket. 56 secured thereto, which engages the outer 'end of'a slide 51 to provide a rest and holding means for the reproducing means.

means in thispositionof rest after the" reproduction of each selected record, `the positiono rest being illustrated in Figures 23 and 24. Aft the selection of a predetermined record in fthe manner lwhich has been mally open contacts 59 to actuate an armature 6|!v and thereby effect the release of the reproducing means H. The amature 60 is preferably in the iorm of a pivotally supported bell crank-as shown 59 are closed when-the notch in the disk 46 registers with the cam portion of the switch operating arm 41. The resulting movement'of the switch` operating arm 41 causes a catch`62which is secured thereto to a'ctuate a switch operating arm 63 to thereby close the contacts 59. The contacts 59 are reopened upon continued movement of the disk 46 which is driven by the cam driving means IN after the reproduction of the selected record.

The preselection for reproduction'of the sidev of away from the reproducing .meansl in the record carrier, necessitates and involves many of the same record selecting operations whichhave been described with respect to the selection and reproduction of the upper face orf a record. They deposit of. a coin in thecoin feed receiver or slide 3i results in the energizing of the electromagnet 31 and the consequent actuation of the ratchet 39 to close the contacts 42 and thereby'start the turntable rotating means Ouand cam driving means N. However, in making the preselection 1 of the face of a record, which is normally faced downwardly in a record carrier, one of `a. pair of switches 64 6:'.65 is closed as will be more fully described in the description of the record pre- L selecting means. 'I 'he closing of` either of the` switches 64 or 65 closes acircuit from the power source to an electromagnet 66 which actuates a latch element 61 and thereby releases a switch operating arm 68 for movement which opens the contacts 69 and-prevents closure ofthe circuit to the reproducing means release magnet 56 through those contacts. .'Ihis prevents the reproducing means release magnet 597frombeingenergized to release the reproducing means when'` thefnotch in the disk46 registers with the cam portionof the switch operating karm v41.

The position of the pin or stud ll on the disk 99 is such that it does not feect relatching of the switch arm 99 with the latch element 91 while the disk is turning to a position o1'V registry of the notch with the cam portion of arm-I1. I'

'I'he registry of the notch in the disk 99 with the cam portion of the switchoperating arm l1 opens the circuit to the cam driving means N and also closes a, circuit from the-power source to the record turning mechanism driving means V through contacts 19 which were partially positioned for closure by the release of the latch element 91. The sequence of operations effected by the record turning mechanism driving means V can be generally followed by reference to Figures 10 to 16 inclusive as well as to the circuit diagram in Figure 2. The driving means V rotates ashaft 12 uponwhich cams 19 and 19 and a record turning arm 1l are mounted for rotation therewith.

Although the detailed mechanisms forefiecting operation of the record turning mechanism will be more fully described, they are set forth gen'- erally here to establish the sequence of operations and the controls for eii'ecting this general sequence. The preliminary movement of the margin of the record as illustrated in Figure 11.

At this stage of the movement of the shaft 12 a cam 99 whichis driven with the shaft 12 .:ooperates with the rotatably supported bell crank 92 `to raise the shaft 12.-arm 19, and record 19 vertically until the record\clears the stud or locating pin 99 on the turntable` as illustrated in Fis-- ure 12. At this upper limit of the movement of theshaft12,apinorstud99,whichissecured to a stationary supporting frame 99 `iits into an opening 99 in a rack-91 which is rotatably mounted on the shaft 12. Theengagement of thepinllwiththeopeningintherackuprevents the rack from rotation with the shaft 12.

The record turning arm 19 includes a rotatably y supported portion 99 upon which the record clips 11, 19, and 19 are moimted and has a rotatably supported shaft portion towhich a pinion gear 99 is drivingly connected. The teeth on the pinion gear 99 mesh with the cooperating teeth on Vthe rack4 91.

The

turning of the record is illustrated in Figures 12, 5 1-3, and 14.

After the record has thus been turned over,

the shaft 12 and turning arm 15, together with the rack 91, are moved downwardly by a compression spring 92; ythe downward movement ci' the shaft by the spring 92 being permitted by the cam 99 and cooperating bell crank 92. 'I'his downward movement of the rack 91 effects disengagement of the rack from the pin or stud 99 so that the rack is again free to rotate with the l5 shaft 12. This downward movement of the arm 19 replaces the record on the turntable G with the locating pin or stud 99 engaging the locating opening in the record. After replacement of the record on the-turntable, the continued 20 rotation of the shaft 12 swings the arm 19 to cause the release of the record by thegriDDers 11, 19, and 19.

Near the end of the swinging movement of the arm 19 arotatably supported element 99 on the end of thearm 19 engages a resilient arm on a switch 99 to close contacts 99 and thereby Also near the end-of the movement of the shaft 12 and record turning arm`19, the cam 19 of the control device Y actuates a switch operating arm 99 to openv contacts 91 and thereby open the power circuit to the driving means V. This actuation of the switch operating arm 99 also opens contacts 99 4andcloses contacts 99 to establish proper connections to the -driving means V for 4 eifecting movement of the driving means V in `a reverse direction upon reenergisation.

inwardly and at the end of this inward movement of the reproducing means the cam portion of the arm l2 registers with the `notchin the disk 99 to close the normally open `contacts 99 and thereby close a circuit from the .power source to the driving means v through 0 the contacts 9 9. This startsthe driving means Vinadirectionreversedtothatinwhichitwas last operated.` The cam driving means N is not started at this time because the circuit thereto producing means H is opened hy the contacta 99. The driving means 5'5 V drives a gear-|99 through a @Operating worm gear |92, which in turn drives the shaft 12. At

the start of the reverse movement of the driving j means V a cam element |99, which-is secured to the gear |99, asshown in Figure 24, engages an endofarotatahlysupportedbell crank |99to move the bell crank. A cable |99 connects the endofthebellcranktotheendofthereproducmovement -of the bell crank which is eil'ected b! g5 the cam element'l99 lifts thereproducing means H and the needle carried thereby vertically away from' the record which has been reproduced.

'Ihis returns there'- 'rs producing meansHvto its position of rest away The reproduction of the record swings the re- 1 ing means H away' from. the needle so that the 14 actuates a switch moves the notch from the record before the return movement of position of rest reopens the starting circuit tov the driving means V.- However, before the contacts 03 are opened and before the movement of the cam 13 of the control device yY has permitted the contacts 09 to be reopened, the cam |to close contacts ||0 and thereby establish an operating circuit to the driving means V. 'I'he switch |09 has an arm which is adapted to register with notches III and ||2 in the cam or disk 14. During the rotation of the disk 'I4 in the counterclockwise direction, as viewed in Figure 2, original turning of the record, the contacts ||0 are held open by the cam or disk 14. However,

This opens the reversed operating circuit to the driving means V to stop the operation thereof. During the reversed rotationof the driving means V the sequence of operations of the record turning arm is the opposite of that which 'was previously describedand the opposite ofthat illustrated in Figures to 16 inclusive. I'he reproduced record is thus replaced in its original position on the turntable G.

After the cam driving means N has been thus started, the operating circuit thereto for the return of the record carrier and turntable is closed through the contacts 43 by the rotation of the notched disk 40 which rein the disk 40 from registry with the cam portion of the switch operating ann 41.

The turntable G passes through the selected record -:arrier during the upward movement `of the turntable to remove the record from the carrier.

During the return of the record to the stack the turntable again moves through the record car,-

Thecam lever |23 is keyed to the snm in so that the shan 1s reciprocable through the cam lever, b ut rotary movement of the cam effects rotation of the shaft |23. This cam lever is actuated by a pin orI stud on the master cam M after the selector shaft has been elevated to the desiredv level for selecting a preselected record to thereby rotate the shaft |23 and I the latch which normally holds the preselected record in position in the stack.

The end of the shaft |23 opposite the selector |22 is rotatablyysecured to a slide plate structure fully described, the .turn of the record carrier and turntable effects In the phonograph disclosedh'erein'the record carriersal are rotatably supported on apost |20 between successive disks |2| in the mounting assembly J.

The master cam M normally holds the slide plate structure |30 in a position such'that the selector |22' is above all of the record carrier latches during the time-when the phonograph is not in operation.

The rotation of the 'plate |34 is limited in one direction by a stop A plurality of rods |35 isreciprocably supported by the selector control frame |25. There are two of these rods for each ot the record carriers J and they are movable one or more at a time to positions in the path of the downward movement of the plate |34 as that plate' moves with the slide plate structure |30. Each of the rods |35 has intermediate its ends three spaced nanges |31, |35, and |33. The anges |3 1'abut the surface of a plate |40 and the flanges |33 and |33 provide limiting stops for the longitudinal movement of the rods |35. The plate |40 is carried rearwardly of the selector frame by pins |42 which project from the plate |45 at its corners and are slidably received 'in sockets in the selector frame |25. Coil springs |43 on each of the pins |42 bias the plate |45 away from theselector frame |25.

The rods |35 may be individually moved into the path of pivoted plate |34 by pushing them toward the selector frame |25. A cancelation rod |44 is slidably mounted in the selector frame |25 and is adapted to actuate a connecting element |45, which is connected to the plate |40 by pins' |45 so that inward movement of the cancelastructure. As previously -mentioned in the general description. the operation of the switches 54 and 55 by the rodsl |35 during the selection of a .record prepares the electricalcontrol device in the circuit of Figure 2 for turning the selected record over.

Upon release of the cancelation rod |44 the springs |43 return the plate |40 to its nor -mal position and zrestore the connecting element and cancelation rod to their normal position.

As the slide plate structure |35 moves upwardly the plate |35 will engage the inner end or ends of any of therods |35 winch may have been the selection of a particular record without turning it over and consequently results in the reprorod |35, the edge |51 is in position to engage the.

pushed inwardly. The pivoted plate |34, however, will be rotated by. engagement with the rods |35 during the upward movement so that the plate will not interfere .with such upward movement. When the slideplate structure |30 moves downwardly, the pivoted plate |35 is in a horizontal position and will engage the uppermost rod |35, which has been actuated for selection to thereby arrest the downward movement of the slide plate structure |30 and selector |22. This stops the selector |22 at the elevation of the record carrier latch for a particular selected record. If none of the rods |35 has been operated, the plate |34 will be stopped just above the pin l|41 at the lower end of the: travel of the side plate structure |35.

Inthephonosraphdisclosedhereinitistobe particularly noted that there are two of the rods |35 in a.pos|tion such that a'particular record carrier will be selected. Oneof the rods |35 for selecting each ofthe record carriers is in al positipa such that 1t engages the plate lu near the outer end thereof.

means 224 and is adapted to. engage the lower end of the 'shaft 12.

Referring particmariy to Figures 1v, 2o, 2,1, 24,

and 25, the normal position of rest of the record turning arm 15 during the intervals between the selection of records is such that the arm 202 is disposed in the extending end portion 206 ofthe guide slot 208 and the detent |84 rests against the inner surface of the sleeve member |10A outof alignment with any of the openings in that sleeve memben During the preliminary movement of the gear |00 and sleeve |10responsive to the operation of the turning mechanism driving means V, the sleeve |10 is rotated from a position such as that indicated in'view a'of Figure 20 to that indicated in view b where the detent engages the inner end `of the opening |86. Upon engagement between the detent,.|84xwith the inner end of the opening |86the shaft 1.2 is moved angularly to a position such fas that indicated in view of Figure 20. During this movement the record turning arm,15 is moved inwardly to grip the edge ofthe record as indicatedin Figures 10 and l1, and the arm 202r is moved inwardly to cooperating cam and bell crank 82` and the as shown in view d of Figure 20. The axial movement of the shaft 12 moves the arm 202 to the top of the guide slot 203. After engagement of the detent |84 with the opening |88 the shaft 12 is again rotated to a position such-as that shownI in view e of Figure 2 0 and the arm 202 is moved to the other side of the guide slot 203. During this rotary-movement of the shaft 12 the rack 81 \is held stationarygby engagement with thefpin 84 so that in addition to the arcuate or swinging movement of the turning arm 15, the shaft 89 and projecting end portion 2 1 `of 'the turning arm are rotated e i At the beginningof the rotary movement of the shaft 89 the detent |98 engages the recess |95 and at the end of this'rotary movement the detent |98 engages the recess |98. The recesses |95 Y and |96 in the shaft 89 provide insurance that the rotation'of the shaft will be the desired 180 and also that the shaftV will not continue to rotate due to the weight of the gripped record on arcuate movement of the record turning arm 15 the arm and record are .moved from the position shown in Figure 12 through that indicated in Fig-4 u such that the detent |84 engages the 'inner end During this rotation and Operation c Although the operation of the phonograph y disclosed herein has been described in connection with the various views of the structurein the drawings, it will be briefly and generally summarized to emphasize certain features and details. In the normal non-playing position of the phonograph the record carriers YJ are in the stacked relation indicated in Figures 1 and 3 and the reproducing means H is releasably latched in a position out of the path of movement of a record which is being selected until that selected record is' in position for reproduction. The rec- Vords are always carried by and returned to the stack with a particular side or selection normally faced upwardly in the carrier.

The reproducing means H is released from its normal position for the reproduction of each record after the record and its selected face have been placed in position for reproduction. After -the reproduction of a particular record the reproducing mean's H is separated from thesurface of the record and swung back to its normal position of rest before the recordis returned t0 its normal position in the stack. Each record is returned to its normal position in the stack afterreproduction.

One or more records or sides of recordsmay be preselected for reproduction prior to the starting of the phonograph, or while it is in -operation. 'lhe records and sides of records will be reproduced in sequence corresponding to the order of displacement of the selector rods |33 from top to bottom of the selector mechanism.
